The Ingredients You will Need:

  • Bone-in leg of lamb

For the Rub: 

  • Paprika
  • Onion powder
  • Garlic powder
  • Black pepper
  • Salt
  • Maggi or Knorr powder
  • Garlic cloves (grated)
  • Fresh rosemary
  • Fresh thyme
  • Extra virgin olive oil (EVOO)

For Chimichurri (optional)

  • Parsley
  • Extra Virgin Olive Oil (EVOO)
  • Fresh Lemon Juice
  • White Vinegar
  • Salt and pepper
  • A dash of Maggi or Bouillon powder
Raw lamb leg and seasoning

 How to Make the Best Roast Lamb Recipe:

  1. Add all the ingredients for the rub in a clean bowl and use a spoon/fork to mix. Set aside. 
  2. Preheat the oven to 425.
  3. Wash/clean the leg lamb and place it on a chopping board or clean surface.
  4. Cut slits into the leg of lamb before marinating to allow the flavor to penetrate deeper into the meat.
  5. While wearing gloves, use your hands, and make sure to rub the marinade into every corner of the bone-in lamb leg, especially into the openings. Finally, insert a few sprigs of fresh rosemary and thyme into the slit openings. You can allow this meat to soak up the marinate before you roast, or you can roast it asap!
  6. Place this seasoned lamb leg in the roast pan. Roast leg of lamb at 425 for 30 minutes uncovered. Then roast covered at 325 for 90 minutes or until done to your desire. Please note that this was a 4 pounds of lamb leg. See my FAQs for tips on how long to roast leg of lamb.
  7. Make the chimichurri while the meat roasts. Start by adding all the ingredients into a clean pan, including some freshly chopped parsley. Taste for flavors and set aside.
  8. Allow resting for 10 – 15 minutes or more before cutting or serving. Drizzle the chimichurri on meat before cutting/serving. This step is optional; however, it gives the lamb roast some fresh, crisp, tangy flavors you wouldn’t want to miss. Alternatively, you can use gravy instead.

Leg of Lamb FAQs

Should I marinate Leg of Lamb for a long time?

Yes, and no. while you can marinate the leg of lamb for hours ahead of roasting, you can easily get away with only seasoning it before cooking. If you have some time, feel free to marinate your leg of lamb for hours before roasting. However, if you are pressed for time, you can season and roast immediately.

From time to time, I get questions about washing meat before cooking. In reality, I suggest you do you. However, I am on “team wash.” I do wash my meat before I make them!

You can allow this meat to soak up the marinate before you roast, or you can roast asap!

Roast uncovered for the first 30 minutes; this allows this meat to develop the perfect crust.
